Multi-Modality Whole Heart Segmentation Dataset (MMWHS) [1]}: this dataset consists of multi-modality whole heart images obtained on different imaging devices at different imaging sites. Segmentation maps are provided for 20 MRI 3D heart images and 20 CT 3D heart images which have domain gap. Following the UDA setup, we use the MRI images as the source domain and CT images as the target domain. We perform UDA with respect to four of the available segmentation classes: ascending aorta (AA), left ventricle blood cavity (LVC), left atrium blood cavity (LAC), myocardium of the left ventricle (MYO).
